#### Operation { #operation }

„Operation“ bezieht sich hier auf eine der HTTP-„Methoden“.

Eine von diesen:

* `POST`
* `GET`
* `PUT`
* `DELETE`

... und die etwas Exotischeren:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

Im HTTP-Protokoll können Sie mit jedem Pfad über eine (oder mehrere) dieser „Methoden“ kommunizieren.
